"6.3 Cm Striated Brass Opera Spyglass"
A perfectly functional opera spyglass. There are signs of wear on the brass varnish and slight dents around the edge of the front lens. To the naked eye, the glass lenses show some fine scratches, dust, and a detachment of the front lens which covers about one-sixth of its surface. Under lamplight, a few stains are visible, but this has little effect on the visibility. Please note that the inner tube is engraved with the manufacturer's name “Bianchi à Paris et à Toulouse”.
